3D model description

This is a reverse bowden setup for the Prusa MK3, the Bear Upgrad-ed or Zaribo extruder in an IKEA Lack enclosure.
I used 2 M6 4mm Fittings and a 2mm/4mm PTFE tube.

You need to drill a hole close to the spool holder through the table.
Then put the cylinder on it from the outside and the printed tube through the hole in the cylinder and the table and secure it from the inside of the enclosure with the printed nut.

After this screw one fitting from the inside into the cap of the cylinder and the other one in the filament sensor cover.

put the PTFE tube through the cylinder and connect both ends to the fittings.

then screw the cap onto the cylinder and you are done

There are two different filament sensor covers. One is for the MK3 original extruder version and the other for the Zaribo mod.
The cover of the bear extruder, made by the fantastic Grégoire Saunier can be found here:

Happy printing :-)
